record screen

I had thought the Mac OS included some sort of quicktime or iMovie function that allowed users to record their screen to, for instance, develop a tutorial on how to do something. In other words, something like windows recorder that would make a movie, recording the video of what windows were open, where you moved the cursor, what you clicked on, while you could narrate the action.

Am I mistaken that this is included or will I need some third-party program?

There are a number of built-in ways to do still captures but don't believe there has ever been a live action screen record on the Mac.
